✍️ Sample PIC Questions & Answers
1. A nuclear gauge operator must maintain a distance of at least how many feet from the gauge when it is in use, according to typical NRC license conditions?
Most NRC license conditions require operators to remain at least 2 feet from the gauge while a reading is being taken to limit radiation exposure.
2. The moisture susceptibility of an HMA mix is most commonly evaluated using which test?
AASHTO T 283 (commonly called the Lottman test) evaluates moisture susceptibility by comparing the tensile strength of conditioned versus unconditioned specimens as the Tensile Strength Ratio (TSR).
3. Why is consistent paver speed important?
Maintaining a consistent speed ensures uniform mat thickness and compaction, improving pavement quality.
4. What is the purpose of the screed in an asphalt paver?
The screed is responsible for spreading and initial compaction of the asphalt to the required thickness and width.
5. What AASHTO test method is used to determine the bulk specific gravity of compacted HMA specimens?
AASHTO T 166 (Bulk Specific Gravity of Compacted Hot-Mix Asphalt) determines the bulk specific gravity of compacted mixtures using a water displacement method.
6. A contractor proposes using type II barricades instead of type III barricades at a full road closure. What is the critical difference that makes type III more appropriate for this situation?
Type III barricades are larger, have three horizontal rails, and provide greater visibility required for road closures, while type II with two rails is typically used for lane closures.
